The reproduction rate, an estimate of the rate at which the virus is currently spread in the community, was estimated on Tuesday to be 1.1.
A value over 1.0 means the virus is considered to be currently spreading or the epidemic growing, because 10 infected people will pass the virus on to more than 10 others.
Not since February has the value been over 1.0. Last week it was estimated to be 0.8.
“This indicates that the epidemic is beginning to increase mildly,” Health Minister Magnus Heunicke wrote on Twitter.
“(The R-number) is backed up by monitoring of sewage water, which shows an increase (in virus levels) in all five regions (of Denmark), especially in Greater Copenhagen,” he added.
Heunicke also wrote on Twitter that “part of the explanation for increasing infections is the introduction of BA. 5 in Denmark,” in reference to the subvariant of the Omicron Covid-19 variant which is expected to become dominant during the summer.
“This subvariant of Omicron comprises a preliminary figure of 32 percent of all confirmed cases in the week commencing June 6th,” he said, adding that the infectious disease control agency State Serum Institute (SSI) was monitoring developments.
Health authorities have so far seen no indications that BA. 5 results in more serious illness than Omicron subvariants prevalent in Denmark last winter.
Heunicke last weekend said that it was “out of the question” for Denmark to reintroduce Covid-19 restrictions this summer.
Health authority figures show that 1,159 new Covid-19 infections were registered during the last daily count. 1,015 of these were in people that have not previously tested positive for the virus.
The cases were found amongst 7,269 PCR tests.
